Question

Найдите координаты вектора c=3a-2b, если a (-1; 5), b (4; -3).

Answer 1

A ( - 1 ; 5 ) 
b ( 4 ; - 3 )
---------------
3a ( - 3 ; 15 ) 
- 2b ( - 8 ; 6 ) 
c = 3a - 2b 
c ( - 11 ; 21 ) 

Answer 2

I can help you with your math problem. To find the coordinates of the vector $$c=3a-2b$$, you need to apply the following formula:

$$c=(3a_x-2b_x, 3a_y-2b_y)$$

where $$a_x$$ and $$a_y$$ are the x and y coordinates of the vector $$a$$, and $$b_x$$ and $$b_y$$ are the x and y coordinates of the vector $$b$$.

Substituting the given values, we get:

$$c=(3(-1)-2(4), 3(5)-2(-3))$$

Simplifying, we get:

$$c=(-11, 21)$$

Therefore, the coordinates of the vector $$c$$ are $$(-11, 21)$$.

I hope this helps. If you have any other questions, feel free to ask me.Ответь+подробно.+Найдите+координаты+вектора+c=3a-2b,+если+a+(-1;+5),+b+(4;+-3).
